The DFSS sealing grease is used in the turbine cylinder binding surface in thermal power plant. It is single component, can remain sticky and will not coking under high temperature, can meet the sealing requirements at maximum, and it is very easy to remove in the next maintenance. It is suitable for high temperature and pressure conditions for smooth, flat cover (butt joint).
DFSS sealing grease can bear high temperature above 685℃, high pressure resistance above 32Mpa, fully meets the requirements of supercritical and ultra supercritical units, is the ideal replacement seal material for the safe operation of large steam turbine units.
High temperature resistance, high pressure resistance, corrosion resistance, dense and tough film, good sealing effect.
Aging resistance, creep resistance, fatigue resistance, no corrosion of cylinder joint surface.
Strong adhesion, easy to apply or remove for maintenance.
Non-toxic and pollution-free.
